V .HOOP- IMPROVEMENT IN SCISSORS-SHARPENERS.

The Schedule referred to in these Letters Patent and making part of thesame Know all 'men by these presents:

` LThat I, CALVIN A. Fos'rnR, of Fitchburg, county of Vorcester andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Scissors-Sharpeners; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings'forming a part of thisspecicat-ion, in which- Figure 1 represents a side view of my improvedscissors-Sharpener, and

Figure 2 represents a plan view of the same.

To enable those skilled in the art to which my invention belongs to makeand use th'e same, I will proceed to describe it more in detail.

In the drawings` A represents the grinding-wheel, which is to be coveredwith a leather band, a, or other suitable material, for receiving emeryor other suitable grinding substance.

Wheel A is supported upon a stud, B, which projects from the inclinedarm C of the detachable frame The lower end of the frame D is made withfour projections, E F b b, for securing the frame to the edge of a tableor projecting bracket, a thumb-screw, G, being tted to the lowerprojection F, for clamping the frame to the edge of the table, while theprojections b b fit against the edge of the table, thereby preventingthe iame from being twisted laterally during the operation of sharpeningthe scissors.

From the upper end of the'fxame D an arm, H,

projects, and has secured to its upper end a slotted inclinedsupporting-piece, I, as fully indicated in the drawings.

The operation is as follows:

The device being attached to the edge of the table J, as indicated inthe drawings, the blade of the scissors to be sharpened is placed uponthe inclined piece I, with its beveled edge upon or against the grindingsurface of the wheel A. A rapid motion is now im parted to thegrinding-wheel, by means of the crank K, with one hand, while theoperator holds the scissors in the other, gradually drawing the bladefrom end to end until the proper cutting-edge has been cbtained.

The device is also very convenient for scouring and burnishing knivesand other similar articles.

A ring, L, is combined with the inclined arm C, which affords a supportto and guides the arms M ot' wheel A as thc latter is revolved.

Having described my improved scissors-Sharpener,

What I claim therein as new and of my invention, and desire to secure byLetters Patent, is-

A scissors-Sharpener composed of the grindingwheel A, detachableclamping-frame D, guiding-ring L, and inclined scissors-supporting pieceH I, said parts being constructed and arranged for joint operaltionsubstantially as herein shown and described.
